Triple-A Reno transferred Hoffmann from its 7-day injured list to the 60-day IL on Thursday while he recovers from an undisclosed injury.
After the Diamondbacks optioned Hoffmann to Triple-A on April 29, he submitted a 6.07 ERA and 1.95 WHIP across 13.1 innings over 12 relief appearances for Reno before landing on the shelf. With his move to the 60-day IL, Hoffmann won't be eligible to return to action for Reno until early August.
